Furthermore, the front-end data collection and analysis can be realized on a global scale. 1) Concurrent acquisition solution on massive test data processing The system involves over 5,500 ATU terminals, 500 sets of testing instruments, and over 20,000 commercial terminals. The instantaneity and accuracy of concurrent data acquisition and processing is an important part for auto drive test. Serial and concurrent distribution mode for processing link is used for data acquisition, and message queue is used for data transmission. 2) Architecture of efficient linear scaling database system According to characteristics of data, the architecture of database system achieves the deployment of multi-node distributed database system by applying the idea of multi dimensional cutting algorithm. 3) Preliminary statistics solution for efficient data processing scheme Preliminary statistics is a moderate processing procedure that test data is presented to user via report or report in unified format. It imposes certain tolerance and analytical ability of unified processing on equipment manufacturers with different devices and chip manufactures. And the index statistics is the key to increase the degree of customer experience in accordance with different dimension indexes. The solution improves the efficiency of data query by acquiring 1T data statistics results within few seconds using the platform.
4) GIS analysis --- automated configuration based geographical grid processing GIS analysis is an extremely important module among data analysis tools. GIS module can provide the users with intuitional presentation of existing network data distribution and geographic basis for drive test analysis, sweep frequency data and network quality optimization. The combination of Flex client and Java server is applied to present analysis results. After the results are processed, the server can release map service and process GIS request from the client. 5) GIS monitoring technology GIS monitoring solution can be utilized without testers, and there are only few numbers of staff needed for monitoring if test positions and operation of big number of test equipment are normal and prevent test failure resulted from equipment problems, save labor cost, avoid repetitive work and improve efficiency. GIS monitoring is utilized to receive the pass-back data (GPS information, information equipment, warming information, event information, MOS information, etc.) in real-time manner, and GPS information and special event information are displayed on Google Map. The system framework is realized by the way of rich client platform, the service part is deployed on the server acquiring the data, and the map display, data processing display and user operations are deployed on the client. 6) State-machine based drive test events determination algorithm The mechanism of state-machine based event determination is changing via the service state. The specification of signaling order can be determined via state machine, error checking and correction functions may be synchronously handled to output events and provide basic business processes data. The solution can restore normal or abnormal events from the network test results. Firstly coordinate with signal analysis to get event, and then determine the cause of the incident according to the analysis on test results. These determinations will contribute to finding and solving problems existing in the network, thereby providing the assistance to network operator with directly improvement on user perception and the quality of network operation. 7) Hadoop-based data processing technology In addition to support national large-scale testing evaluation, powerful means are also systematically provided in the aspect of operation depth. 25 * 25 m rasterized processing is taken in key areas including cities, villages, towns, scenic spots, universities, industrial parks and others, forming nearly 80 million basic grid data.

Comparatively, Auto Test Management Platform with a centralized data acquisition, processing and analysis greatly reduces manual intervention thanks to the method of automatic data acquisition, statistics feedback and analysis applied.
Given that daily consumption of gasoline is approximately 60 liters, drive test consumes 10,560 liters for 22 days in 8 months per annum. Highly integrated remote testing module is embedded with eight test modules without configuring a large number of single-mode terminals, realizing synchronous acquisition of multi-channel data. Compared to only two test equipment in each vehicle by artificial drive test method, automatic drive test can save 31,680 liters of gasoline with regular density of test road, simultaneously reducing workload and corresponding vehicle and fuel consumption, making positive contribution to the slowing of global warming by reducing carbon emissions. With optimization of the system architecture, 5 private cloud servers (200w per hour) and 10 PC servers (400w per hour) can be saved due to application of load balancing server and reduction of peak load. Fewer cabinets are expected to access to the system with centralized server room layout. Approximately, (200w*5+400w*10)*24*30*365=1,314,000 degrees can be saved annually.
